The way Leverkusen expected the match was not how it was for them from the starting till the end, and this was why Leverkusen easily lost focus after Lookman scored the first goal. Leverkusen is used to absorbing pressure even when you are winning them. They will come back in the second half and draw the match or win it.
It was different in the case of Atalanta, because they were playing with pressure and Atalanta didn't give them any opportunity to penetrate their defense making it more frustrating for them. Maybe it is because it was a final match and the players lack the experience of playing in the finals.
one thing that I will always remember is that Leverkusen was not ready to compete in the final round at that time.
I mean, usually Leverkusen in every match from the preliminary round to the semi finals, Leverkusen appearance looks very confident in providing quite good resistance but when they have difficulty attacking, Xabi will definitely provide a defensive strategy to end the match in a draw.
but in yesterday's match, it was clear that Leverkusen did not have the option to defend or attack and looking at the mentality of the Leverkusen players they looked nervous and not confident which made all the Leverkusen players frustrated.
not only that, after conceding the first goal, Leverkusen tried to put up resistance but ended in failure again when the Leverkusen players lacked focus when in front of Atalanta goal.
after that, Leverkusen became more and more deadlocked, tried to attack but the defense became weak, but tried to defend, but Atalanta attacks became bigger.
some people say Leverkusen has very good ball control but for me if someone saw the live match at that time they would definitely say that Atalanta had more possession of the ball and gave them the opportunity to score 3 scores.
